282 THE CANADIAN ENTOMOLOGIST. 



following is allied rather closely to comatus, but is a larger and differently 

 coloured species : 



P. centralis, n. sp. — Stouter thin comatus, highly polished, pale 

 luteo-flavate, the head dusky except anteriorly, the pronotum with a large 

 central piceous cloud, and the elytra more or less piceous along the suture 

 and side margins ; pubescence long and dense beneath, long but sparse 

 on the pronotum anteriorly and at the base of the elytra, the lateral 

 fimbriae long and dense ; head less coarsely punctate ; prothorax with more 

 numerous coarse punctures anteriorly, and with the fine punctures more 

 distinct ; elytra feebly but inconstantly sculptured, with the three or four 

 double lines frequently wholly obsolete. Length, 14. 5-1 6.0 mm.; width, 

 7.5-8 2 mm. California (Kaweah, Tulare Co., 1,000 feet). 



Comatus is more northern in habitat, being abundant in the regions 

 about Sacramento. Testaceus, of LeConte, from the Island of Sta. Cruz 

 (Proc. Acad. Phila., VI, p. 346), is probably, at any rate, a well-marked 

 subspecies of comatus, and should be continued in our lists as such ; the 

 antennae are described as 10-jointed in the male, but, according to that 

 author, they are o-jointed in the female. So possibly all my specimens are 

 females. The subject would seem to be worthy of renewed study by those 

 having more ample material. 



Dyscinetus, Harold. 

 The following is much larger and stouter than trachypygus, Burm.: 



D. puncticauda, n. sp. — General characters as in trachypygus but 

 more finely and sparsely sculptured, black, polished ; head similar, but 

 with the clypeus not finely and sparsely punctured but coarsely, though 

 superficially and confluently, punctalo-rugose ; prothorax rather more 

 transverse, finely and very sparsely punctate ; elytra similar, but with the 

 double series of punctures scarcely at all impressed ; pygidum ( $ ) highly 

 polished, coarsely and sparsely punctured throughout, the punctures 

 becoming close and irregularly confused near the lateral angles. Length, 

 ct , 18.5-20.0 mm.; width, 9.0-10.7 mm. Kansas (Hamilton Co.), F. 

 H. Snow. 



The sculpture of the pygidium differs entirely from that oUrachypygus, 

 but resembles that of the West Indian picipes, Burm., which is said to 

 occur also in Mexico by Bates. I am inclined, however, to think that 

 Bates had the present species before him, or one closely allied, and not 

 the true picipes, as the legs in puncticauda are black or concolorous, and 

 the anterior margin of the clypeus, though broadly sinuous, could not by
